1. There are moral absolutes.
2. They have been revealed by God.
3. The revelation is clear regarding murder and the sanctity of human life.
4. This act was clearly wrong.

Well, I guess that algorithm copes with this simple situation, but it doesn't scale to the general case because it can deadlock at stage 2 against another process that's been told the opposite by their god. It's also something of a security risk, as it's wide-open to abuse by gods revealing stuff to promote their own agendas.
